David Gergen: “The fact is the Republicans have been losing the message war on this. They are, everybody knows that.”

You can't out-Nixon Nixon very easily, but Donald Trump has.

I don't think Trump is out of the woods, even though his poll numbers are not only staying up, they have actually been strengthened some.

If he had a receptive audience, and I will tell you, when everything -- when all the facts were to come out, it would be like Nixon and the tapes.

If he comes out and throws cold water on this, then I don't think it goes anywhere.
